BEARING BRASS FOR TOP ROLLS AND SUPPORT THEREFOR.

Application filed January 16, 1924. Serial No. 686,530.

To all whom it may concern:

Be it known that I, IRA S. Games, a citizen of the United States ofAmerica, and resident of Martins Ferry, county of Belmont, and State ofOhio, have invented certain new and useful Improvements in BearingBrasses for Top Rolls and Supports Therefor, of which the following is aspecification. V

This invention relates broadly to roll bearings and more specificallytoa top bearing for rolling mill rolls.

The primary object of the invention is to provide a readily removableand insertible support or carrier for the top journal brasses of rollingmill rolls.

A, further object is to provide a toproll bearing brass support orcarrier which permits a limited amount of endwise movement of the brasscarried thereby, whereby binding between the inner end of the brass andthe fillet of the roll is in large measure prevented.

A still further object is to provide a device of the character mentionedwhich is insertible in and removable from its place on or in the rollhousing from the outer side of the latter, thereby greatly reducing andfacilitating the work of mounting new brasses and removing worn brassesas occasion requires.

With these and other objects in view, the invention resides in thfeatures of construction, arrangements of parts and combinations ofelements which will hereinafter be fully described, reference being hadto the accompanying drawings, in which Figure 1 is a longitudinalsection of the invention, illustrating its application to the roll androll housing;

Figure 2 is a bottom plan View of the invention applied, showing theroll removed and the housing in section; and- Figure 3 is an inner endelevation of the invention, applied.

Referring to said drawings, 1 indicates a roll housing having thereinthe usual vertical passageway 2 in which the neck 3 of the top roll 4:is received and is vertically movable. Disposed in seated relation tothe top of the roll neck 3 is a top roll bearing brass 5 which isrigidly carried on the under side of a metal block 6 of rider type,being preferably of dove-tail form and fitting a correspondingly shapedchannel 7 provided therefor in said block. Said block is longitudinallymovable on said roll neck 3, being slidab'ly mounted upon a supportwhich comp-rises horizontal arms or guides 8 rigidly carried by andextending inwardly from a horizontal transverse bar 9 which is adaptedto be mounted against the outer face of the housing 1 with its oppositeends received by supporting brackets 10 carried upon the said outer faceof the housin at opposite sides of said passageway 2. aid arms or guides8 are received within channels or mortises 11 provided in the oppositelateral edge portions of the under face of said block, and similarmortises 12 provided in the opposite lateral edge portions of the thebrass 5 and said fillet is greatly reduced,

if not wholly eliminated, thus to a large -'extent reducing theliability to roll breakage resulting from excessive friction due to suchbinding. The extent ofsuch sliding move ment in an outward direction maybe adj usted by means of an adjusting screw 15 directed inwardly throughthe bar 9 and adapted to have the adjacent end of the block 6 abutagainst its point at the outward limit of movement.

The guide members 13 have directed downward therethrough pins or bolts16 which have their ends received in longitudinal' chanels 17 providedtherefor in the underlying portions of the block 6. Said bolts 16, soreceivedin said channels, while permitting unobstructed sliding movementof the block throughout a predetermined range, cooperate with the innerends of said channels for preventing chance withdrawal, or displacement,of said block with respect to its supporting frame.

From the foregoing, it will be understood that the top roll bearingbrass 5, the rider block 6 and the supporting frame are together, or inassembled relation, introduced in and removed from operative positionwith respect to the neck of the top roll from the outer side of the rollhousing, and that, as a consequence, the work of effecting suchintroduction and removal is greatly lightened and facilitated.

The brackets 10 have therein longitudinal slots 18 through which theirattaching bolts 19 ar directed. When desired, the top brass and rider 6may be raised and supported in an elevated out-ofthe-way position bysaid brackets, the attaching bolts first being loosened, said bracketsthen being elevated to any extent allowed by said slots 18, and saidbolts finally being retightened for retaining said brackets in theirelevated positions.

vl'fhalt is claimed is" 1. A top roll bearing brass and a carriertherefor, comprising a supporting frame embodying a bar adapted to bemounted horizontally against the outer face of a roll housing, parallelguide members carthe passageway in which the roll necks are received, aplurality of parallel guide members carried by said bar and extendinghorizontally inward through said passageway, a rider-like blockslid'ably carried by said guide members, and a top roll bearing brasscarried on the under side of said block.

3. The combination with a roll housing, of

afbar adapted for mounting on the outer face of-sai-d housing atopposite sides of the passageway in which the roll necks are received, aplurality of parallel guide members carried by said bar and extendinghorizoirtally inward through said passageway,

arider-lilre block slidably carried by said guide members, adjust-ablemeans for limit ing the extent of outward movement of said block, and atop brass 'c'arri'edon the under side of said block, and supportingmembers for said bar mounted upon the housing, said members permittingvertical movement of said bar.

4. The combination with a roll housing having supporting brackets omitsouter face at opposite sides of the vertical passageway in which theroll necks are received, of a vertically movable bar having its oppositeends received between said brackets and the housing, a pluralit ofparallel guide members carried by sai bar and extending inward from thelatter through said passageway, a rider-like block supported by andlongitudinally slidable on said guide members, means for limiting theextent of Slidi 'IJQIIIOVGTHQHt of said block, and a top bearing brasscarried on the under face of said block.

'5. The combination with roll housing having supporting brackets on itsouter face at opposite sides of the vertical passageway in which theroll necks are received, of a vertically movable bar having its oppositeends received between said brackets and the housing, a plurality ofparallel guide members carried by said bar and extending inward from thelatter through said passageway, a rider-like block supported by andlongitudinally slid'abl'e said guide members, said block havingguideways therein in which said guide members are received, means forlimiting the extent of sliding movement of said block, and a top rollbearing brass carried on the under face of said block.

In testimony whereof, I a-fiix my signature in presence oftwosubscribing witnesses.
